SPECIFICATION forming part of Letters Patent No. 352,304, dated November9, 1886.

Application filed November 12, 1885. Serial No. 182,513. (No model.) I

To all wiwm it may concern:

Be it known that l, WALTER S. DAVIS, a citizen of the United States,residing at Contoocook, in the county of Merrimack and Slate of NewHampshire, have invented certain new and useful Improvements inPaper-Box Machines, of which the following is a specification.

My invention relates to machines for making paper boxes of variousdimensions, the object of my invention being to provide in a machinemechanism by which boxes may be formed (exceptingthe cover) entire fromthree pieces of card or straw board, which are previously cut the properdimensions to form a box of a given size and placed in their re spectivereceptacles, from which they may be delivered formed into boxes,pastedtogether, and carried singly from the machine by the saidniechanisin with great rapidity.

My invention consists in the combination of the various mechanismsnecessary for carrying the different parts from which a box is to beformed to their proper place, forming and pasting the said partstogether and depositing the completed box upon a suitable carrier orcarriage, by which said box may be removed from the machine, all ofwhich will be clearly described in the following specification, andillustrated in the accompanying drawings, forming part thereof.

Figure 1 represents an end elevation of my improved machine, Fig. 2being the rear side elevation. Fig. 3 is a vertical {section takencentrally from front to back of the machine, and showing one of the cardboard receivers partially filled. with those parts which form the bodyof a box and the reciprocal and rotat-ive mechanism. The parts arecarried singly from said receiver to their proper po sition under theplunger or former. Fig. 4 is I an end sectional elevation, which betterillustrates the actuating mechanism applied to those three feed-rollswhich are shown in Fig. 3 as mounted upon the end frames, and theirrigid connections. Fig. 5 is asectional plan view of a portion of theframe of the machine, the adjustable tables between which a box isformed, the screw-rods and gearing by which said tables are operated,and the feed-rolls which were shown in Fig. 4. Figs. 6 and 7 table.

are respectively a side elevation and plan view of the sliding blocks,adapted to movein grooves formed in the adjustable tables, and

to carry the adjustable stops provided thereon 5 5 for preventing thoseparts which form the body of a box from moving beyond the re quiredlimit under the former. Fig. 8 is a plan view of a crossframe whichcarries an adjustable bed-table, an adjustable table upon 6c which thereceivers for those parts composing the ends of a box are secured, and aslide for carrying said parts to their destination, ready to be pastedto the body of a box. Fig. 9 is a cross-section of all above line Y Y,Fig. 8. Fig. 10 is a sectional view showing the former in a position toform a box, one of the pasterolls in readiness to apply paste as itpasses down, the card-boards which are to form the ends of a box intheir proper position relative to the said former, and also the adjustablebed- Fig. 11 is an enlarged sectional view showing the pasteboxes and rolls in end elevation and the mechanism by. which they aredrawn toward a box in order to place a layer of paste thereon.

Fig. 24 is an enlarged elevation of one of the pressure-plates by whichthe ends of a box are stuck to the body thereof, conneeted to a sectionof the lever by which it is operated. Fig. 25 is a section of one ofsaid levers, having connected to its lower end the actuating mechanism,consisting of a cam and horizontal levers. Fig. 26 is a plan view of aportion of the actuating mechanism for said vertical levers, showingsections of that portion of the frame of the machine upon which saidmechanism is mounted. Fig. 27 is an en- .larged elevation of one of thebevel-gears and pinion by which the vertical shafts driving the partsshow n'in Figs. 13 and 14 are operated. Figs. 28 and 29 are respectivelyan elevation and plan view of either of the slotted arms which aremounted upon the top of said vertical shafts, and which are connected bysuitablesliding blocks to the slots shown in thesaid parts Figs. 13 and14. Fig. 30 illustrates one manner of constructing an adjustable former.(Shownin elevation.) Fig. 31 is a plan view of same. Fig.32 is aperspective view of a partly-completed box.

Like reference-letters indicate corresponding parts throughout thevarious views.

The frame may be of any convenient design, and consists of suitableuprights, A A, and various connecting parts, to be mentioned asopportunity offers in the following description. The pieces ofcard-board which form the bottom and sides of a box, after being cut tocertain dimensions, are first placed in the receptacle B, which islocated at the back of the machine, from which they are fed out throughslot b at the bottom of the pile, singly, toward and between thefeed-rolls-O O, the mechanism by which this movement is obtainedconsisting of a serrated rack or frame, B, and suitable means by whichit may have a reciprocating motion to and away from the feed-rolls O G,a convenient method for accomplishing this being shown best in Fig. 3 ofthe accompanying drawings, in which b is a block connected at its top toa portion of the frame B, its bottom being swiveled' to a slide, D, theouter end of which is connected by swivel to a lever, E, fulerumed aboutmidway from either end thereof to the under side of one of the parts aof the frame, as at E. In order to transmit a rocking motion to theopposite end of said lever, said end is slotted lengthwise, said slotbeing long enough to afford suflicient play to a bolt, 0, or othersuitable connection, which passes through the slotted end of said lever,and the free end of an arm, F, which is revolved horizontally by asystem of bevelgearing andshafts connecting with the counter-shaft G. Ifdesired, the arm F may be constructed with a slot for rendering itsconnection with the lever E adjustable, and thus givin g a varied stroketo the feeding serrated frame B. This receptacle B may be made in someapproved adjustable form relative to its width andlength, in order thatit may readily accommodate itself to the various dimensions ofcard-board required for different sizes of boxes; or different-sizedreceptacles'B may be provided for use, as required. The feed-rolls C Care mounted in bearings formed in either of the upright frames A A,suitable springs, 0 c, exerting a pressureupon thejournals of the roll 0toward the roll 0. These are connected by spur-gears H H at one end, theroll 0 being provided outside of the spur-gear H witha bevel-pinion, I,meshing with the bevel-gear J, mounted on upper end of vertical shaft J,hung in suitable bearings and cdnnected at its lower terminus with thedriving'shaft K by bevel gears j j, by which said feed-rolls receivetheir motion. When these pieces of card-board which form the bottom andsides ofa box shall have passed the feed-rolls G 0,

they enter between trucks L L, which carry them as far as the adjustablestop-pieces M, secured to the adjustable forming-tables N. The trucks Lare one-half inch (more or less) in thickness and three inches (more orless) in diameter, and are mounted upon one end of either shaft 1 insuitable bearings, one of which is formed upon the under side of saidtables N, and the other of which is provided upon either of the parts aof the frame, said trucks L projecting through slots n in either of thetables N, so that their periphery shall be one-quarter inch (more orless) above the upper surface of the said tables, as seen in thedrawings.

The outer ends of either of the shafts l are provided with belt-pnlleysl, which are connected by belts with the pulleys 0 mounted near eitherend of the feed-roll G, as seen in full lines, Figs. 1 and 2, anddottedlines, Fig. 3, by which motion is communicated to the trucks L.The upper trucks, L, act merely as pressure-rolls to keep the card-boardin contact with the trucks L, and they are designed to drop directlyover the said trucks L, in order that their work may be the niosteffective. The last-named rolls must of necessity'move with theadjustable forming-tables, which is provided for by splining the pulleysl to the shafts I, so as to admit of the necessary adjustmentlongitudinally of said shafts 1. Some provision must be made for a likeadjustment of the trucks L, which will be hereinafter ex plained.

The tables N rest upon the parts a of the frame, and in order thatthey-may be adjusted relative to the width of box required to be made,between which tables said box must pass downward while being formed,said tables V are made somewhat longer than the distance from eitheroutside edge of the parts a, and upon the under side 'of theseprojecting ends are formedlugs n,to which are threaded the screwrods 0,mounted ill bearings 0 near either end thereof and secured to theoutside edge of either of the uprights A A, one of said rods with itsbearings being shown in Fig. 2. The

lugs n on one of the tables N will be tapped by which it may beoperated.

35 of the slides q.

5 direction the said tables may be moved apart,

and when rotated in the opposite direction they will be drawn towardeach other. This is accomplished by a light horizontal shaft, P, mountedin bearings P, secured to the outside of the upright A, and providedwith wormgears 19, meshing with spur gears 0, mounted on one end ofeither of the screw-rods O, as shownbest in Fig. 1. Said shaft P is alsopro vided upon one end with a suitable crank, 19', When the said piecesof cardboard which form the bottom and sides of a boX shall have beendeposited upon the forming-tables N in their proper position, they mustbe forced down between said 20 tables by a suitable die or former inorder to bend up the sides thereof. This may consist of a rectangularwooden block or hollow iron or metal box, Q, of the proper dimensions,as seen best in Fig. 3; but in order to avoid the necessity of providinga separate plunger or former for the various sizes of boxes capable ofbeing made by this machine I prefer the construction illustrated byFigs. and 31 of the drawings, in which the parts q q form a 30cylindrical hub, the contacting surfaces of either of the parts q 9'being grooved for the reception, respectively, ofthe adjustable slidesq" (1 which are placed as seen in Fig. 31, the slides q being above andresting upon the tops On the outer ends of either of the slides q" arehinged suitable right-angle pieces, q, their heights corresponding tothat of the deepest box the machine is capable of making. The lowerslides, q", are provided in like manner on either outer end withright-angle pieces g Thus to adjust said right-angle pieces q" to anygiven size of boxthe operator has simply to move them to or away fromthe parts q q and rotate the latter in opposite directions, when. thebolts g", which pass through the parts (1 q, may be tightened, theright-angle pieces (1 Q5 set, so that either their sides or endsrespectively may be parallel, and the adjust-able die or former will beready for use.

5 end of the bar R enters and is secured to a cross bar, It, by rivetsor bolts 1', and the necessary vertical movementrequired by the die orfornr er Q, is communicated to the cross-bar It by the vertical bars S,located outside of either of 6a the uprights A A, the upper ends ofwhich are pivoted to the ends of said bar R, their lower ends beingconnected to the bar S, pivoted to the uprights A A, for the purpose ofmaintaining the bars S as nearly as possiblein 6 a vertical positionwhile moving up and down,

the pivot 8, connecting said bars S S, projecting far enough on theoutside of the same'to carry the friction-rolls s, which entercamgrooves it. formed in the gear-wheels T, mounted upon either end ofthe counter-shaft G and meshing with the pinions Ir, mounted upon thedriving-shaft K.

The cross-frame a is adapted to carry suitable sliding frames, U,fittedto ways formed thereon. Horizontal adjustable shafts'u, carryingthe pressure-trucks L, are fitted in the lower end of said frames U, andby means of a set-screw, a, threaded to said frames and acting upon saidshafts a, the operatoris enabled to adjust the trucks L relative to thetrucks L, as previously mentioned. As the pieces of card-board uponwhich these trucks L L operate must be bent in order to form the sidesand bottom of a box, it becomes necessary that the upper trucks, L, mustbe raised out of the way before the die or former Q operates upon saidcard-board.

Before describing the mechanism by which the said rolls are'raised itmay be well tohere state thatt he peculiar form of the cam-grooves t inthe gear-wheels T which in practice Ifind most preferable is such thatwhile the said wheels T are making one quarter-revolution the die orformer Q is detained at its highest elevation, the nextquarter-revolntion bringing said die or former th ence downward to itslowest limit of movement, the next or third quarter-revolution detainingthe said die in the last-named position, while the fourthquarterrevolution carries the said die back to the first-named position,or its highest limit ofmotion.

' The mechanism by which-the frames U, carrying the trucks L, areoperated is dependent for its motion upon that of the bar R, carryingthe die Q, and consists of the following parts:

A horizontal shaft. V, having bearings V secured upon one side of thecross-frame a is provided at either end with arms 1;, which pass thencethrough vertical slots or openings a", formed in the sliding frames U,and connect at their free ends with the bars WV, the other ends of saidbars being pivoted, as at a to the said frames U, and midway from eitherend thereof with ashort arm, 12, adapted to be acted uponby the verticalbar r, bolted at its upper end to the rectangular bar R, as shown bestin Fig. 3, in which View the die or former is shown at its highest pointof stroke and the vertical bar'r resting upon the short lever 22. Now,with the downward movement of the former Q, the bar r, resting .u )onthe lever i) must necessaril force the latter down also, thus raisingthe arms a, and, by reason of the connecting-levers W, the frames U totheir upper limit of movement, as in Fig. 1, and this, too, before thesaid die or former Q shall have reached the formingtables N in itsdownward course, thus fulfilling for the. trucks L the necessaryrequirement before stated. By this means, also, the said trucks L areheld in their elevated position until said die or former' during itsupward stroke shall have passed the-said formingtable N.

Suitable slides, or, are secured to the forming-tables N, as shown inFigs. and 10, in such convenient manner as to render them capable ofadjustment thereon relative to the required length of a box, for thepurpose of bending over the ends of the bottom and sides of the same ahalf-inch, (more or less,) as shown in perspective view, Fig. 32, ofthat portion of a box upon which the ends may be pasted. In Fig. the dieor former making its downwardstroke is shown to have reached a pointjustbelow the top surface of the forming-tables N a sufficient distance tohave started the formation of the sides of a box,

. which are shown bent upward on about a forty-fivedegree angle. Theends of the bottom and sides of said box have also been partiall y bentover by contact with the slides a. As the die or former continues tomove downward the bent ends, previously referred to, of the bottom andsides of the box are coated with paste by pasterolls X, said rolls beinglocated directly underneath the forming tables N, one at either end ofthe die, and mounted in suitable paste-boxes, X, their frames :1: extending far enough at either end to rest and slide upon the parts a ofthe machine-frame. One side and top of the pasteboxes X are cut away,and the paste-rolls X so mounted therein as that while they arepartially submerged in the paste their cylindrical surface will pro- 5ject slightly beyond the side of the paste box,

as clearly shown in Fig. 12 of the drawings. Thus when said paste-boxesare moved to their operative position the paste-roll only comes incontact with the card-board box being formed. In order to bring saidpaste-rolls in contact with the box being formed only when said box ismoving downward past said rolls, right-angled levers 1 are provided,which are ful'crumed at 2 to the uprights A A, as shown best in Fig. 11,their-short ends pivoted to suitable extension-rods, 3, by which thepasteboxes X may be adjusted relative to the required length of a box,the opposite ends of said extension -levers 3 being pivoted at aconvenient point to the frames as of the pasteboxes, the longer end ofsaid right angled levers 1 fitting slots formed in and near the top ofvertical bars 4, having neartheir bottom suitable means for preventingany lateral movement of the same, as at 5, Fig. 11, and provided attheir lower end with rolls 6, bearing upon cams 7, said cams beingmounted upon the counter-shaft Gjust inside either of the uprights A A.One of the journals of either paste-roll X projects a trifle beyond thepastebox. Upon these are mounted chain-pulleys 8, which are driven by asuitable chain, 9,

passing under one and over the other of said.

pulleys, (so that they may be rotated in opposite directions,) andthenceover pulleys 10, conveniently attached to either of the parts a of theframe, and under asimilar pulley, 11, mounted on driving-shaft K.

The card-board forming the ends of a box, after being cut the requiredsize, is deposited in receptacles 12, consisting of plates 13, havingvertical walls 14 15,-and adjustable wall 16, a tongue, 17, being formedat the bottom fitting groove 18, running longitudinally in the topsurface of the table 19, upon which said plates 13 rest, and to whichthey are secured and rendered adjustable relative to the length of agiven box by the screws 20, passing through the same and threaded tonuts 21, fitting slots 22, formed longitudinally in the said table 19.

In order to adjust the vertical walls 14 14.

relative to a 'box of given width, against one side of which the saidwalls'14 must be brought in contact, the table 19 is adjustably mountedupon the bed-frame 23by means of grooves 24, adapted to receive tongues25, formed upon top of said bed-frame 23. The said table 19 is renderedcapable of being fastened whereever required by a suitable screw, whichmay pass through slot 26, running transversely in said table, and bethreaded to the bed-frame at 27.

The mechanism by which the pieces of cardboard forming the ends of a boxare delivered from their receptacles 12 consists of the slides 28,having dovetailed tongues 29, fitting corresponding grooves, 30, formedin one side ofthe walls 15, as seen best in Figs. 17, 22, and 23, andhaving arms 31, the outer ends of which are mounted upon rods 32,rigidly secured to suitable stands, 33, mounted upon one end' of theadjustable slide 34, which moves in suitable ways, 35, formed upon theunder side of the bed-frame 23, as in Fig. 15 of the drawings, said rods32 being sutficiently long to admit of proper adjustment of the slides28 relative to a box of given length by aid of the set-screws 36. Theslides 28 occupy openings .left for the purpose between adjustable walls16 and rigid walls 15 and a portion or section of the walls 14 and 15,as clearly seen in Figs. 17 and 18. That part of the slides 28 whichcarries the card-board out of the receptacles for a distance of slightlymore than the length of the said cardboard is rabbeted on the sideopposite to the tongues 29 to a depth of from one thirty-second toone-sixteenth of an inch, (more or less,) thus forming a shoulder, 23,as seen in Fig. 23, against and by means of which a piece of card-boardmay rest and be borne toward and to its destination, as also seen inFig. 23; or these slides may readily be made adjustable relative to therequired length of the card-board ends for a given box by mak ing saidrabbetof greater length and inserting an adjustable plate of steel, 38,which may form the shoulder 23, the latter method (see Figs. 10, 15, and28,) having secured l a layer of paste, as previously stated, byfolwithin said slots 40 suitable connections; 41, which enter slots 42,formed in the-adjustable slides 34, and by which said slides 34 aregiven a reciprocal motion with the rotative motion of said arms, aremounted upon top of vertical shaft 43, carried in bearings 44 45, asseen in Fig 2, the lower end of said shaft being provided with thebevel'pinion 46, mesh ing with the bevel-gear segments 47, constructedas shown in detail, Fig. 27', their pitch diameters being four to one,or one to four, respeetively-i. 6., the larger gears '47 having justteeth enough to cause the pinion 46 to make one complete revolution, andthis while the saidgear 47 is making butone quarter-revolution. By thisarrangement the slides 28, after the gear 47 has been properly set onthe counter-shaft G, are enabled to deliver the cardboard ends of a boxto their proper position, and return to position shown in Fig. 2 beforethe forming-die Q, carrying the bottom and sides of a box, shall havereached in its downward course but little beyond the paste-rolls X, thusavoiding contact with the said delivery-slides, which would otherwiseoccur. To insure the perfect operation of thesedeliveryslides,.provision must be made whereby a certain amount ofpressure is continuously applied to the card-board pieces contained in.the receptacles 12. This may be accomplished in various ways, one ofthese being shown in Figs. 22 and 23, in which a follower, 48, is placedin either .of the said receptacles, having an arm, 49, provided with aslot, 50, running lengthwise therewith, said arms extending beyond theopenend of said receptacles and having connected to their outer ends acord, 51, passing over grooved wheels 52, and thence downward throughslot 50 of said arm 49, where they may be attached to suitable weightsof proper power to supply the required pressure to the saidfollower-plates 48. Said wheels'52 are mounted upon rods 53, supportedin bearings 54, secured to the said receptacles 12. To avoid anyinaccuracy in depositing these card-board pieces contained in saidreceptacles, they are carried slightly beyond their proper position bythe delivery-slides 28 and against the stopplate 55,. which is hinged,as seen in Fig. 16, to one of the forming-tables N, in such a positionas thatit may hang a little off or away from the forming-die, exceptduring the time the paste-rolls are distributing paste, as previouslydescribed, when, by reason of the connecting-rod 56, slide'bar 57 and aprotuberance, 58, formed upon or attached to the vertical actuating-bar4, said stop-plate is forced with the last of the upward and the firstpart of the downward motion of said bar4 into a vertical position, andthus places said card-board pieces so that their ends come exactly flushwith the sides of the box, which by this time has reached the bed-table,to be hereinafter described. These card-board pieces are then pressedagainst those parts of the bottom and sides of the box which havereceived lower-plates 59, operated by the levers 60, fulcrumed at 61 tothe uprights A A, their lower ends being connected by means of a forkedlink, 62, to a bar, 63, having in its opposite end a suitable stdd, 64,which may enter. a cam-groove, 65, formed for this purpose in the sideof one of the wheels 66, both wheels 66 being mounted side by side uponthe counter-shaft G, as seen in Figs. 2 and 26, each op erating one ofthe levers The bars 63 are carried in bearings 67, having caps 68, asshown, and rigidly fastened between parts a of the frame, which areconnected at either end to the parts a.

The follower-plates 59 may be connected to the levers 60, with a view tothe necessary adjustment required relative to the length of a given box,in a simple 1nanner,-as seen in detail, Fig. 24. To the outside of thesaid follower-plates is hinged one end of a rod, to which is threaded acollar and two check-nuts, one at either end of said collar, said collarbeing connected to the upper end' of said lever 60, as shown.

The levers 60 are composed of a framework, which affords the opening 69,as seen in Fig. 2, the obj ectof which is to provide a passage for awide belt, upon which the boxes as completed maybe carried away from themachine. This is rendered possible by the movement of the bed-table 70,which is carried uponways 25, formed upon the bed-frame 23, and isprovided with aslot, 71, running transversely therein. A suitable arm, 72, of the same construction as the arm 39, being likewise slotted andconnected at 73.to the slot 71 insaid bedtable, is mounted upon thevertical shaft 74, carried in bearings 75 76, and provided at its lowerend with a bevel-pinion, 77, meshing with a bevelgear segment, 78,mounted upon the counter-shaft G. In this manner a reciprocal motion iscommunicated to the'said bedtable 70, and its forward and returnmovement is made while the counter-shaft G is making onequarter-revolution in the same manner as does the slide 34, the pinion77 and gear-wheel 78 being made from the same pattern from which thepinion and gear 46 47 are made. The moment the pressure plates 59 shallhave pressed the heads onto the box they plate 55 also eased off, asseen in Fig. 10, and the bed-table 70 removed from under the forming-dieQ, the completed box thereupon dropping through the bedframe 23 betweenthe slideways 25 and upon a carrier-belt, as previousl y stated, orother suitable means for removing the said boxes from said machine.

The sliding nuts M are providedfor the adjustable guide-stops M, theslots in said parts M fitting the rectangular part at of the nuts. Athumb-nut, m, being threaded to thestud m which, by aid of the flange mprojecting from said nut on the under side of the slot 12.

IIC

are both simultaneously removed, the stopformed in the forming-tables N,said guide-stop M is held in any position desired.
